CALIBRATION 

 
 
The voltage setpoints may be altered in the field to suit particular customer 

requirements.  Adjustments are provided to adjust the main battery voltage at 

which the paralleling solenoid is energized.  An additional adjustment permits 

adjusting the voltage below which the auxiliary battery will not be paralleled for 

starting boost.
